【摘要】：直流電源系統(tǒng)在電力系統(tǒng)中有非常重要的作用，它通常是指由蓄電池、變流器以及其它輔助電路組成的供電系統(tǒng)。在提供直流電源供電的區(qū)域，他們要求直流電源能夠運(yùn)行穩(wěn)定，更高的要求是工作中調(diào)節(jié)方便，并能對(duì)其進(jìn)行遠(yuǎn)程監(jiān)控。本文基于烏海地區(qū)變電站直流電源監(jiān)測(cè)系統(tǒng)現(xiàn)狀，深入研究和分析直流電源遠(yuǎn)程監(jiān)測(cè)系統(tǒng)的關(guān)鍵技術(shù)，對(duì)原直流電源蓄電池系統(tǒng)進(jìn)行改造，實(shí)現(xiàn)對(duì)其遠(yuǎn)程監(jiān)控，提高變電站直流電源系統(tǒng)的自動(dòng)化水平、完善其功能，增強(qiáng)直流系統(tǒng)運(yùn)行的安全性和穩(wěn)定性的目的。 在電力系統(tǒng)中，直流電源系統(tǒng)是變電站的重要組成部分，也關(guān)系到電氣設(shè)備的操作與控制。由于直流系統(tǒng)設(shè)備繁多，分布分散，經(jīng)常需要維護(hù)和監(jiān)測(cè)，本文提出了一種直流電源智能化在線遠(yuǎn)程監(jiān)測(cè)技術(shù)，能夠?qū)崿F(xiàn)將蓄電池組各個(gè)工作模塊的實(shí)時(shí)數(shù)據(jù)采集并傳回控制中心。該方案不但能夠大大降低維護(hù)人員的工作量，，同時(shí)能夠?qū)χ绷髟O(shè)備實(shí)時(shí)監(jiān)測(cè)，能夠隨時(shí)把握蓄電池組的工作狀態(tài)，提高了變電站整體運(yùn)維水平。 在本文中，對(duì)系統(tǒng)監(jiān)控終端軟件和子站監(jiān)測(cè)通信模塊進(jìn)行設(shè)計(jì)，通過(guò)監(jiān)控終端能夠監(jiān)控和瀏覽所有現(xiàn)場(chǎng)數(shù)據(jù)，通過(guò)直流系統(tǒng)模擬圖觀察直流設(shè)備運(yùn)行狀況，并且能夠遠(yuǎn)程調(diào)控母線電壓的狀態(tài)切換，觀察電池溫度及充放電情況，電池電壓和電流可以通過(guò)表格形式形成數(shù)據(jù)圖，查看歷史數(shù)據(jù)進(jìn)行對(duì)比，能夠通過(guò)監(jiān)控軟件更改現(xiàn)場(chǎng)模塊參數(shù)等。
[Abstract]:DC power system plays an important role in power system. It usually refers to the power supply system composed of battery, converter and other auxiliary circuits. In the area where DC power supply is provided, they require DC power supply to run stably, and the higher requirement is that it can be adjusted conveniently and can be monitored remotely. Based on the status quo of DC power monitoring system in Wuhai substation, the key technology of DC power remote monitoring system is deeply studied and analyzed in this paper, and the original DC power battery system is reformed to realize remote monitoring. The purpose of improving the automation level of DC power supply system in substation, perfecting its function and enhancing the safety and stability of DC system operation. In power system, DC power supply system is an important part of substation, and also relates to the operation and control of electrical equipment. Because the DC system has a lot of equipments and distributed, it often needs maintenance and monitoring, this paper presents a kind of intelligent on-line remote monitoring technology of DC power supply. It can collect the real-time data of each working module of battery group and send it back to the control center. This scheme not only can greatly reduce the workload of maintainers, but also can monitor the DC equipment in real time, grasp the working state of the accumulator at any time, and improve the operation and maintenance level of the substation as a whole. In this paper, the system monitoring terminal software and sub-station monitoring communication module are designed, through monitoring terminal can monitor and browse all the field data, through the DC system simulation diagram to observe the operation of DC equipment. And can remotely adjust and control the bus voltage state switch, observe the battery temperature and charge and discharge situation, battery voltage and current can form data graph through tabular form, check the historical data to compare. Be able to change field module parameters by monitoring software.
